Re: Cluster on Disk - Status ?

[Troy Rose]

Well, Carsten, nobody said that MySQL Cluster needed RAM - just memory.

If you have relatively fast disks (say, Ultra 320's), that might be in a RAID - striped configuration, why not create a swap partition of anything up to 16GB? There would be a performance hit, nobody's questioning that, but it turns an in-memory cluster into an on-disk cluster. That's the configuration I'm currently working with in a test environment, and it seems to work without a hitch - simply fooling the ndb components that they actually have 4GB of memory, when in reality there's only 1 GB on each node.
